Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic wastewater treatment, in particular to TDS evaporation treatment equipment for fluorine-containing wastewater in photovoltaic cell production. Background Art

[0002] Fluorine is one of the essential trace elements for the human body. Trace fluorine can promote children's growth and development and prevent tooth decay. It is a normal component of bones and teeth, a material element necessary for the formation of enamel, and also has a protective effect on osteoporosis. However, excessive intake will cause serious harm to human health. With the development of modern industry, a large amount of high-concentration fluorine-containing industrial wastewater is discharged. These wastewaters generally contain fluoride ions, which will cause pollution of water bodies, soil, and groundwater. Fluorine pollutants will be enriched in soil, terrestrial plants, and aquatic organisms, causing great long-term harm to the environment, which has aroused strong concern. At the same time, a large part of industrial fluoride-containing wastewater contains a lot of salt, especially in the photovoltaic industry. The TDS in fluoride-containing wastewater is generally high, threatening human drinking water safety.

The amount of wastewater after treatment is still large, and during the evaporation process of the wastewater, the fluoride ions in the wastewater are easy to adhere to the surface of the heating equipment, affecting the heating effect of the equipment.
